Click and Call From Your Web Browser, Google Voice For Chrome:

Google updated its Voice extension for Chrome on Friday, allowing people to call phone numbers directly from the web browser. If you love Google or hate retyping phone numbers, this one's should be for you.

One of the great things about upgrading to a smartphone years ago was that all numbers were links. The updated Voice extension for Chrome allows for a similar streamlining in your browser.

The extension basically just turns phone numbers into clickable links, eliminating the need to cut and paste them across windows. It also adds a phone icon to Chrome, letting you quickly place calls and choose the number from which you do so. While it's a nice step toward a lazier future, there are some caveats. Mac  users, for example, will need to install the latest Chromium build, not just the regular old Chrome, to gain the functionality.
